Hayward® HPD Pulsation Dampeners

The HPD Series features all thermoplastic construction with multiple bladder material options and is designed and built to extend the useful life of critical components, including pumps, flowmeters, and sensors, by lessening the effects of pressure surges. The HPD Series reduces adverse shock created by a pump action in a chemical feed system, which results in an even, laminar flow and continuous dosage.
